  [clang][Interp] Emit const references for Float arguments (#79753)

The Float print type is backed by the Floating class, which in turn uses
APFloat, which might heap-allocate memory, so might be expensive to
copy.

Add an 'AsRef' bit to the ArgType tablegen class, which defines whether
we pass the argument around by copy or by reference.
